Events+ widget for upcomming events show's event concepts in some cases

Hi,

When the widget Upcoming Events is activated some event concepts are displayed in the widget.

Widget settings: display dates, excerpt & thumbnail. Limit 5, lookahead 52 weeks and any category.

Event concept: Repeats each month on the 9th day at 10 o clock and the event is 2 hours long.

In that case the concept is shown in the widget.
Clicking the url in the widget shows a page not found, so thats okay.

When the concept is just on 1 day (no start or end date) it's not shown in the widget.

You can see the widget here in the sidebar on the right side.

Greetings,
